ALBERT RAMMOSER, OF BERLIN, GERMANY, ASSIGNOR TO GEORGE LOETVENBERG, OFSAME PLACE.

AUTOMATIC GAS-LIGHTING APPARATUS FOR INCANDESCENT GAS-LIGHTS.

SPECIFICATION forming part of Letters Patent No. 582,875, dated May 18,1897.

Application filed November 2, 1896. Serial No. 610,877- (No model.)

To aZZ whom it may concern:

Be it known that I, ALBERT RAMMOSER, a subject of the German Emperor,and a resident of Berlin, Germany, have invented certain new and usefulImprovements in Automatic Gas-Lighting Apparatus for IncandescentGas-Lights, of which the following is a specification.

My invention relates to appliances for gaslighting; and it consists ofthe hereinafter-described device for automatically lighting the fiame ofan incandescent burner.

In the accompanying drawings, Figure 1 is an elevation, partly sectionalview, of an incandescent gas-light burner provided with my improveddevice for automatic lighting. Fig. 2 is a diagrammatical illustrationof a modified construction of the lighting device. Fig. 3 is a sectionaland Fig. 4 a top view of another modified construction thereof.

In the construction shown in Fig. 1 the incandescent mantle A is hung onthe hood H, made of some incombustible material and supported on theforked pin T. The top of the hood is contracted into a cylindrical domeH, surmounted by the conical apex H and in top thereof is provided asmall opening 0.

Post P is held by ring P on the cylindrical dome H, and to this post issecured a pellet Z, made of self-igniting material in the manner asdescribed in my United States patent, granted November 24, 1896, No.572,093. The ends of loop C, made of plaited platinum wire, are embeddedin the self-igniting pellet Z. The loop extends downward over the hood.

The incandescent mantle closes around the hood H, and when the cock isturned on the gas and air entering through the burner B will flow upwardin mantle A and stream quite forcibly through the opening 0 against theself-igniting pellet Z.

The flow of gas will ignite the pellet, and the heat produced therebywill be quickly communicated to the loop 0. About the same time the gasescaping through the meshes of the mantle A will fill the chimney D, and

then the glowing platinum loop will ignite it. The flame produced willflash downward and ignite the combustive mixture accumulated underneaththe mantle. As soon as the gas is ignited within the mantle no more ofit will flow through the aperture 0, (the whole supply being consumedwithin the mantle,) and consequently the glowing of the self-ignitingpellet Z and of the platinum-wire loop 0 will cease. This is animportant feature of my invention, inasmuch as thereby the life of theself-igniting pellet and also of the platinumwire loop G is preserved.

In the modified construction shown in Fig. 2 the self-igniting pellet Z,with the loop 0, is secured to wire 19, sustaining the hood H, withmantle A secured thereto.

111 the top of the hood H is a similar aperture O, and the operation ofthe self-igniting device is the same as described above.

In the modified form shown in Figs. 3 and 4 the top of the hood H isprovided with a wider aperture, and a Wire sieve L, made of fineplatinum wire or produced of some finely-perforated incombustiblesubstance, is spread over it. The self-igniting pellet Z, withplatinum-wire loop 0, is set on this sieve L, and the device operated ina similar manner as described above.

I claim .as my invention and desire to secure by Letters Patent 1. Adevice for automatically lighting incandescent gas-burners, comprising aglobular hood, supporting the incandescent mantle, and having anaperture in its apex, a selfigniting pellet, arranged above the openingof the hood, and a loop of plaited platinum wire, having its endsembedded in the selfigniting pellet.

2. A device for automatically lighting incandescent gas-burners, adaptedto be sus pended in the path of the current of gas above the upperorifice of the incandescent mantle, comprising a self-igniting pelletand a loop of plaited platinum wire having its ends embedded in theself-igniting pellet.

3. The combination with an incandescent gas-burner having theincandescent mantle I my invention I have signed my name inpressuspended on a hood having an orifice in. its once of twosubscribing Witnesses. top, of a self-i 'niting pellet, secured above '1the orifice of the hood, and of a loop ofplnited ALLER l RAMMOSER'platinum Wire having its ends embedded in \Vitnesses: the self-ignitingpellet. \V. IIAUPT,

In testimony that I claim the foregoing as EDUARD FRANKE.
